Filed Mar. 13,1962, Ser. No. 179,355 3 Claims. (Cl. 81-125) The present inventionrelates to tools generally and in particular to a socket Wrench ot thescrewdriver type.

An object of the present invention is to provide a useful tool adaptedto Istant bolts and the like in hard to reach places, one which hasmeans for retaining a bolt in the tool until the bolt is stamted in itsposition a bolt hole, and one which is highly elective in action.

Another object of the present invention is to provide a hand tool of thescrewdriver type which may be employed with long or short bolts, onewhich serves to free the hand of the user in starting bolts or the like,and one which can be manufactured in quantity at reasonable cost.

A further object of the present invention is to provide a screwdrivertype magnetic tool having replaceable sockets so as to accommodate boltheads of various sizes, the magnetic portion ot the tool being operablewith any size socket desired.

These and other objects and advantages of the present invention will befully 'apparent upon consideration of the following description of thetool of the present invention, the description 4to be considered in thelight of the drawing attached, in which:

FIGURE l is a cross-sectional vie-w of the tool of the presentinvention,

FIGURE 2 is a view partially in section showing the tool in use,

FIGURE 3 is a view taken on the line 3 3 ouf FIG- URE 1,

FIGURE 4 is la view .of the portion of the tool showing how a bolt isheld in a straight position,

FIGURE 5 is a sectional view of a modified form of the socket portion ofthe tool,

FIG-URE 6 is la view taken on the line 6-6 of FIG- URE 5, and

FIGURE 7 is a view similar to FIGURE 5 showing a larger socket in use onthe tool of the present invention.

yReferring in detail to the drawing, the socket wrench of the presentinvention comprises an elongated hollow body 10 preferably fabricated ofya non-magnetic material. In the form of the invention shown in FIGURESl to 4, inclusive, the body 10 has one end llared out to form a socketconstituting means on one end of the body 10 adapted to engage the headof a bolt, the flared out end portion being designated by the referencenumeral 12 and the bolt being designated by the numeral 14.

A handle 16 is carried on the other end of the body 1l) and preferablyis fabricated of plastic material or the like.

One end of the handle is formed with a bore 18 of a size to receivetherein the adjacent end portion oi the body 10 and the other end of thehandle i16- is provided with a threaded bore 2li having a diameter lessthan the diameter ot' the bore 18. The bores 18 and I20 are disposed inlongitudinal alignment with the inter-lor of the body 10 and iareconnected in communication therewith.

A rod 22 has a threaded portion 24 adjacent one end threadably engagedin the bore 2i) of Ithe handle 16. A knurled wheel 26 is mounted uponthe free end of the rod 212 adjacent the -threaded portion 24 andprovides a means for gripping the rod 22 order to rotate it within thehandle l16 to advance or retract the rod 22 with respect to the body 10.

The other end of the rod 22 remote from the knurled 3,126,774 PatentedMar. 31, 1964 ICC wheel 26 carries a magnet 28 of a diameter to slidablylit within the bore Slt ot the body 10.

In the form of the invention shown in FIGURES 5 to 7, inclusive, thebody 1d is provided on its lower end with an outwardly bent lug element32 received in a recess 34 provided in the stem portion 36 of aremovable socket 38.

In FIGURE 7, a socket 38 is shown of a greater diameter than the socket38 shown in FIGURES 5 `and 6. The stern 36 of the socket 38 lits on theend of the body 10 as in FIGURES 5 and 6r.

In use, the magnet 28 is insertable into and withdrawyable from thesockets 12, 38, 38 by turning the rod 22 within the handle 16. Thispermits the tool lof the present invention to position la fasteningelement such as the bolt 14 in position adjacent the hole to receive itand to start the bolt 14 with ease and facility.

In FIGURE 4 it will be seen that the bolt 1&4 might be ata cocked angleprevious to seating on the magnet `28 but that the magnet |28 will holdthe bolt in ya straight position as in FIGUR-ES l and 2, after themagnet has contacted the head of the bolt.

The tool of the present invention makes it possible for bolts of alllengths and sizes to be started in inaccessible places whene the lingersmay not be able to hold the bolt and it also frees the hand of the userwhich normally would have to hold .the bolt while a wrench was applied.

Sockets of Yall sizes may be provided tor use with the tool and it isexpected that numerous changes and modications may be made the inventionas will be found practical Without departing from the spirit of theinvention as set forth in the appended claims.

What is claimed is:
